...Though shipping is still the most resource-efficient way to move containers, large ships use some of the dirtiest fuel on the planet. Ships' bunker fuel is a thick, black sludge leftover from the refining process and has about 2,000 times the sulfur of regular diesel fuel. When bunker fuel burns, it releases a host of toxins, including sulfur oxides and nitrogen oxides, that can lead to respiratory problems and acid rain. Now a better understanding of the health impact of shipping and commercial boats - combined with high oil prices and tighter general pollution restrictions - is sparking what could...
...world's first cargo ship partly run on solar power. With 328 solar panels covering its upper deck, the ship produces enough electricity to continuously power 10 homes and can be used to transport 6,400 cars at a time. Though the ship still primarily relies on bunker fuel, it's a step toward the company's goal of zero emissions by 2050. NYK Line already has its next green transport in mind: the Super Eco Ship 2030, a concept ship that uses solar sails to lower CO2 emissions...
...Even the U.S. Navy is making greener warships. On Oct. 24, the U.S.S. Makin Island - dubbed the Navy's Prius - was formally commissioned. It was built with a gas turbine that drives an electric generator, and the Navy says these engine advances will save nearly $250 million in fuel costs over the vessel's lifetime. On its first trip from Mississippi to California, it consumed 900,000 gallons less fuel than a conventional warship...
Speaking at MIT on Oct. 26, President Obama besought MIT students and students at colleges all across America to tackle the “challenge of their generation” by pursuing research in alternative fuel sources and technologies and other methods of combating climate change and obtaining independence from foreign sources of oil. We appreciate the president’s calling upon young people to engage the critical issue of energy independence and hope that students at MIT and other universities answer this call. We also endorse the current effort on Capitol Hill to pass climate-change legislation. However...
...your story on Yumi Someya: you don't need to go to Japan to find people using biofuel. My son has been collecting oil from local restaurants and converting it to diesel fuel for his truck for years. The vehicle runs well, the process is relatively simple, and it costs him next to nothing. Dian Woodroffe, SHREWSBURY...
